COURSE of the MONTH

bandwidth

hello,
I have two server 1 in fedora core v4 and the other is centos v4.4
I would like to have some kind of software installed on them
so that it can generate graphs of the total bandwidth used of day, week, month..
and also the peek with time in it! so that I can know if I need a 50MB/PS connection
or 100mbit etc.. something like this http://www.hybodus.com/images/bw_graph.png

do you have managed switches that can mirror traffic from one port to another.

only reason I ask is if you want a little more precise bandwidth statistics, Ntop is great. The detail of MRTG is it takes a sample every 5 minutes and averages it over the five minutes. Whereas, Ntop you can see minute by minute. Plus you can break it down by protocol, so you know how much bandwidth say SMTP or HTTP traffic takes up. As well as real time tracking of connections so you can see who is taking up so much bandwidth at the current moment and what they are doing.

yes.. you need to install mrtg or cacti to make this graphs.... and you need access to the router or a snmp public community in your router. is very simple if you have this. and you can find many tutorials in the internet, how to install it.
